so you are indicating the server should be accessed by someone,or some thing i completely unknow 5 times in 3 days? and the data should be modified?what if there are massive data inside this server? i am working with an none safe tool to store my data?this is a PC,not a com or org server.which means there should not be a targeted visit.and this is what bothers me a lot. well ,when seeing 2 people coming up to you ,one you've already known and the seconed you do not know,with out any official introdution,will you trust the second guy? PS:you people all use linux?
